American reality television star Kim Kardashian cropped out Kylie Jenner's rumoured boyfriend Tyga from a picture taken at French Montana's birthday bash in Los Angeles.

The 34-year-old Keeping Up With The Kardashians star posted a photo on Instagram without the rapper, and captioned it: #Family #HappyBdayFrench."

According to TMZ, Kim disapproves of Tyga as she is good friends with his ex-fiance Blac Chyna.

"Tyga didn't really know Kim had an issue with him hanging out and working on projects with Kylie. Tyga thought he was cool with Kim and everybody else in the family. He doesn't have a problem with Kim, but he's not about to let her dictate his life or allow her to trash him to her sisters and the rest of the family," a source told Hollywood Life.

"Tyga doesn't understand why Kim is bothered by his friendship with Kylie. He thinks she's overreacting, but whatever.... He's going to be him, regardless," the insider added.

Rumours that the Rack City rapper and Kylie are dating started after they were spotted at Kabuki Japanese Restaurant in Los Angeles' Woodland Hills area.

"Kylie isn't dating anybody. This whole little group of kids who have been around forever, and I call them kids because, relatively speaking, they kind of all travel as a pack and they enjoy each other's company," she shared. "We all live in the same neighborhood. [Tyga] used to live across the street for a long time, and now he lives next door to Khloe."
